The owner of a McLean mansion on the Potomac River has foreclosed on the 20,000 square foot house, named just months ago the third most expensive home in the D.C. area by Washingtonian magazine.

The home, at 201 Chain Bridge Rd., will hit the auction block at 11:30 a.m. Sept. 27 in the Arlington County Circuit Court Courthouse. (The home is actually located in Arlington County, but carries a McLean address and a McLean ZIP code.)

According to Arlington County Property records, the property has been owned by entrepreneur Rodney Hunt since 2003. It includes "10 fireplaces, elevator, high ceilings and massive windows that expose breathtaking views and plentiful natural light. A beautiful gourmet kitchen with huge center island is ideal for entertaining family and friends. The kitchen offers exquisite cabinetry and quality countertops. The relaxing master suite features a private balcony with incredible views."

It also features a "detached guest house and staff quarters, basketball court, men's gym and showers, separate ladies gym and spa, steam showers, saunas, indoor exercise pool, billiards room, two lane bowling alley, movie theater and ample parking options with a 15-car underground garage and private three car garage," according to the auction listing.

Arlington County last assessed the property—which spans two lots, 201 Chain Bridge Rd. and 189 Chain Bridge Rd.—in 2012. The combined estimated value of the lots is approximately $23.1 million.
